Here is your friendly Google Ai: ‘No, penetrators do not use spent nuclear fuel directly. They primarily utilize depleted uranium (DU), which is a byproduct of the uranium enrichment process. While spent nuclear fuel contains uranium, it also contains other radioactive materials and is not typically repurposed for penetrators. Depleted uranium, on the other hand, is primarily composed of U-238 and has a high density, making it suitable for armor-piercing projectiles.’ The false belief, that using such ordinance provides security from nuclear warefare, is evident when such weapons can be carried in a briefcase! #Penetrators #NuclearWeapons
